>>5 replies and nobody wants to say what they personally try to do or why.
I fly with the string pointing slightly out of the turn. I do this
because the glider seems to balance nicely that way and require less
control input. I don't think the glider climbs any more slowly because
of this.
>>Who is ultimately responsible?

Absolutely, but is that what the OP was talking about?
Surely, as a sport, it's also incumbent on us, the participants, to
make sure that gliders are not overweight and pilots don't exceed the
permitted limits.
Or does that mirror
Only in the USA?
By all accounts, you would have all this and more if you overfly
